But we need suggestions for replacement terms too. Creation is nature (although the supratemporal 'heavenlies' is also creation, so by nature is often meant 'temporal creation').

Secular can also be an ideology or practice that imagines a non-religious sector of life.

In stead of "full-time Xian ministry" we should go back to the terms distinguishing the ecclesial "ordained" minstry (elders/bishops[pastors/teachers] and deacons) and non-ordained. In political community we properly distinguish between "rulers & subjects" or better, "government & citizenry". This distinction holds in almost every societal sphere. The church has it too.

So, I don't mind "clergy" for the ordained and "laity" for the non-ordained. Laity is derived from a word for "the people." Clergy are the "clerks".

I think we do need a way to refer to those who get paid to do ministry, as opposed to those of us who get paid not because what we do is ministry but because of some other reason. It's true that the second category ought to be seeing everything we do as ministry, but there is a distinction here that's worth recognizing. Thsoe we call full-time ministers are being paid to do what they do precisely because it is ministry. I am ministering through teaching philosophy at the college level and challenging students and philosophers in a way that I hope serves the gospel, and the way I live my life in these settings and everything else I do will ideally be part of my ministry. But I'm not getting paid to do what I do because it is ministry. I just happen to do it in a way that I intend will also count as ministry.
